The VBA Script to Update Access VBA Saved Imports Exports

Here’s the UpdateImportSpecPathXML script to update Access VBA saved imports exports:

Public Sub UpdateImportSpecPathXML(ByVal strSpecName As String, ByVal strNewPath As String)
    
    Dim xmlString As String
    Dim xmlDoc As Object
    Dim xmlNode As Object
    Dim newPath As String
    Dim projectPath As String
    
    ' Get the project path
    'projectPath = CurrentProject.Path
    
    ' Define the new path
    'newPath = projectPath & "\NWEDAILY.txt"
    
    ' Get the XML string representation of the import/export specification
    xmlString = CurrentProject.ImportExportSpecifications(strSpecName).XML
    
    ' Create a new XML document object
    Set xmlDoc = CreateObject("MSXML2.DOMDocument")
    
    ' Load the XML string
    xmlDoc.LoadXML xmlString
    
    ' Set the namespace for the document
    xmlDoc.SetProperty "SelectionNamespaces", "xmlns:ns='urn:www.microsoft.com/office/access/imexspec'"
    
    ' Select the ImportExportSpecification node
    Set xmlNode = xmlDoc.SelectSingleNode("//ns:ImportExportSpecification")
    
    ' Update the Path attribute
    xmlNode.Attributes.getNamedItem("Path").Text = strNewPath
    
    ' Save the updated XML back to the specification
    CurrentProject.ImportExportSpecifications(strSpecName).XML = xmlDoc.XML
    
    'MsgBox "Path attribute updated successfully."
    
End Sub

How the Script Works

1. Retrieves the XML string of the specified import/export specification.
2. Creates a new XML document object and loads the XML string.
3. Sets the namespace for proper XML manipulation.
4. Selects the ImportExportSpecification node.
5. Updates the Path attribute with the new file path.
6. Saves the updated XML back to the import/export specification.

To update your saved imports exports, simply call the script with the specification name and new file path.
